While parked and idling in a parking lot with passengers in vehicle, there was a sizzling sound followed by a flame flicker observed directly behind the driver's side, rear passenger seat at the bottom of the rear, driver's side glass panel. Shortly thereafter, the rear, driver's side glass panel shattered. My vehicle has rear sliding glass and only the driver's side panel shattered. Smoke and burning smell was noticeable. After online research, I discovered the GM recall #N192220470 related to 159,000 Canadian vehicles. My situation matched the description of this recall exactly, but according to GM, my VIN# is not included in the recall. My vehicle is currently at my local Chevy/GMC dealer for diagnosis and repair, but they don't seem to have much concern about the safety failure and told me the repair is not covered by warranty. To me, this is a serious design flaw and poses a potentially dangerous safety issue.

According to my local GMC dealership (West herr), this is a common problem that GM isn't covering.
